A 6.9 coarse earthquake hit the Salomon Sea on Saturday, according to the United States Geological Survey. A “threat of tsunami” was published for certain parts of the Côte de la Papua Nouvelle-Guinée.
The American tsunami alert system said that waves of 3 to 10 feet above normal tide levels were possible near the epicenter of the earthquake. The system has not expressed alerts for places elsewhere in the Pacific Ocean.
The Temblor occurred at 6:04 a.m. from Papua New Guinea to around 121 miles south-east of Kimbe, in Papua-Nouvelle-Guinée, the USGS data show.
While seismologists examine the available data, they can revise the indicated scale of the earthquake. Additional information collected on the earthquake can also encourage scientists to the USGS to update the Shake-Severity card.
Replicas in the region
A replica is generally a smaller earthquake that follows a larger one in the same general area. Replicas are generally minor adjustments along the part of a flaw that slipped at the time of the initial earthquake.
Quakes and replicas within 100 miles
Replicas can occur for days, weeks or even years after the first earthquake. These events can be of an equal or more important scale for the initial earthquake, and they can continue to affect the already damaged locations.
When earthquakes and aftershocks have occurred
Source: United States Geological Survey | Notes: the categories of tremors are based on the Modified mercalli intensity ladder. When repair data is available, the corresponding cards and graphics include earthquakes within 100 miles and seven days depending on the initial earthquake. All times above are the time of Papua New Guinea. Shake Data is from Saturday April 5 at 6:20 a.m., Papua Nouvelle-Guinée time. Replica data is from Saturday April 5 at 8:34 a.m. Papua New Guinea time.
